# User onboarding

This guide walks you through onboarding a user in the Investment API. It includes user creation, regulatory checks and regulatory identifiers.

Our flexible regulatory checks ensure that the onboarding process only takes a few seconds instead of days.

## Prerequisites

- You can start onboarding users as soon as you have completed the steps listed in the ["Getting started" tutorial](/products/tol/getting_started/preparation_and_start_up).
- Onboarding for businesses is not supported, but will follow soon. Currently, we only support onboarding and opening securities accounts for individuals.
- Support for information on the user’s tax residency and the Common Reporting Standard (CRS) is currently under development and will follow soon. Currently, we only onboard users that are non-US persons.
